OSCILLATING DEVICE Original Filed July- 26, 1923- Sheets-Sheer 2 Patented cc. 1?, 1329 OSOILLATING DEVICE Application filed July 26, 2923, Serial This invention relates to an oscillating device particularly adapted for washing machines, and consists in the matters hereinafter described and more particularly set forth in the appended claims.

In the accompanying drawings Fig. 1 is a side elevational view of said mechanism as applied to washing machines;

Fig. 2 is an enlarged vertical sectional view taken on line 22 of Fig. 1;

Fig. 3 is a top plan view of the parts shown in Fig. 2 with the container omitted; and

Fig. 4 is a vertical sectional View taken on line 44 of Fig. 3.

The device of my invention has a base or stand 1, provided with two laterally spaced, upright standards 2, 2. Located between the standards 2, 2 at or adjacent their upper ends, is a member 3, which as shown in the drawings takes the form of an open frame or ring,

although it may have any other shape desired. Said member 3 is arranged to extend across the space between the standards 2, 2

and is pivotally connected therewith at op posed points by pivot pins or trunnions 4, 4.

These, as shown in Figs. 3 and 4, are in the form of bolts inserted through the standards 2, 2 from the outside with clamp nuts 5, 5

on the inner ends inside of the member or frame 3. Where the bolts 4 pass through said member 3, the latter is machined or otherwise provided with circular bosses 6, 6 making fiat bearing surfaces for the nuts an standards, respectively.

Arranged above the member or frame 3 is a platform 7. This'may have any shape desired and, as shown in Fig. 3, is built on square lines to support a square bottomed container 8. The platform 7 is connected with the members 3 at diametrically arranged points between the pivot pins or trunnions 4, 4, as shownin Fig. 3. Said platform comprises flat plates 9, 9 on opposite sides of the trunnions 4, 4 and integrally or otherwise rigidly 5 secured to the member 3. The container 8 may be releasably secured to said plates 9, 9, the latter being in the same plane. The articles to be washed are placed in the container 8 with a suitable quantity of soap and water through an opening 10 in the top wall of the No. 653,974. Renewed may 10, 1929.

container. This opening is closed by a removable lid ll. The member 3 and platform 7 constitute a walking beam to support the container.

The base or stand 1 is provided with a top plate 12 and side members or supporting legs 13, 13. Extending through the plate 12 is a Vertical shaft 14 journaled at its lower end. in a case 15 hung from the under side of the plate 12. Said shaft 14 extends above the plate 12 into the space between the standards 2, 2 and is disposed with its axis between the ends of the beam and intersecting the tilting axis of the beam at the center thereof and also parallel to the plane in which the beam tilts. The shaft 14 carries at its upper end a member 16 having spaced ears 17, 17 extending upward therefrom and between which extends a block or member 18. Said block 18 is fixed between the ears 17, 17 by a pin 19.

Extending diametrically across the ring 3 at right-angles to the trunnions 4, 4 is a shaft 20 with its ends journaled in said ring. On the shaft 20 is a sleeve 21 fixed thereto by pins 22. Said sleeve 21 is provided over the center of the shaft 14 with a downwardly extending tubular projection 23 open at its lower end to receive the upper end of an inclined connecting rod 24. Said rod 24 is fixed by a pin 25 or otherwise in the tubular projection 23 and has its lower end extending through the block 18 at a point offset outward from the pin 19, as clearly shown in Figs. 2 and 4. The rod 24 extends loosely through the block 18 and is held from being drawn up from the same by a pin and washer 26, 27 on said rod below the block 18.

For rotating the shaft 14, an electric motor 28 is employed. This is hung from the under side of the top plate 12 or secured to the case 15 in position to have its armature shaft 29 horizontal or transverse to the shaft 14 and at one side of the same. A direct drive is had between the armature shaft 29 and the shaft 14 by a worm 30 on the former meshing with a worm wheel 31 on the latter, as shown in the drawings.

In operation, the rotation of the shaft 14 carries the lower end of the permanently inclined rod 24 continuously in a circular path around the axis of said shaft 14 in eccentric relation thereto, and effects the tilting of the beam or frame 7 on trunnions 4, 4 in opposite directions in a single plane only at right-angles to the axis of said trunnions. This causes the container 8 to be tilted or oscillated with the frame or beam to agitate the contents of the container. When the rod 24 is brought into the position shown in full lines in Fig. 2, the frame or beam 7 with the container 8 are tilted-to the opposite side of the axis of the trunnions 4, 4, as shown 1n full lines in said Fig. 2. When the rod reaches a position on the opposite side of said axis,'as indicatedby the; dot and dash line a of Fig. 2, the beam 7 and container 8 are tilted to the opposite side of said'axis, as indicated by the dot and dash lines I) in Fig. 2. The sleeve 21 in rocking with the shaft allows the lower end of the rod 24 to be carried around with the shaft 14'between the positions just described, without binding through the beam. As the rod is carried between these positions, it rights the frame or beam 7 and its container 8 to a horizontal position on each quarter turn of the rod between these positions, as shown in Fig. 4. The rod 24, as shown in the drawings, is at an angle of approximately20 degrees to the axis of the shaft 14. x Y

When used in connection with a washing machine, the axis (44) of the tilt im parted to the container 8 is below the bottom wall of the latter. The result is that the entire body of water in the container is above this axis and is thus agitated throughout its entire mass. It follows, therefore, that sufficient agitation or throw-of the water and articles therein is gained to effectively accomplish washing purposes.

While I have shown and described the device of my invention as used for oscillating or tilting the container of a washing machine,

' it is of course to be understood that my inventionis-not to be so limited, in that the device may be used for a 'tating any liquid or' material.
